Feature Request: Multisite Exclusion Patterns

[kristineds]

It would be nice if we could add a new Comet Cache Option panel for Multisite networks that would allow a network admin to exclude Comet Cache from certain sub-sites.

• Before this line add the following:

  'exclude_hosts' => '', // Empty string or line-delimited patterns.

• Before this line add the following:

  case 'exclude_hosts': // Converts to regex (caSe insensitive).

• Before this block of code add this new block:

  if (!defined('COMET_CACHE_EXCLUDE_HOSTS')) {
      /**
       * Host exclusions.
       *
       * @since 16xxxx Adding host exclusions.
       *
       * @var string A regular expression; else an empty string.
       */
      define('COMET_CACHE_EXCLUDE_HOSTS', '%%COMET_CACHE_EXCLUDE_HOSTS%%');
  }

• Before this block of code add the following new block:

  if (COMET_CACHE_EXCLUDE_HOSTS && preg_match(COMET_CACHE_EXCLUDE_HOSTS, $_SERVER['HTTP_HOST'])) {
      return $this->maybeSetDebugInfo($this::NC_DEBUG_EXCLUDED_HOSTS);
  }

• Before this block of code add the following new block:

  /**
  * No-cache because the current request is excluded by its host name.
  *
  * @since 16xxxx Host exclusions.
  *
  * @type string A unique string identifier in the set of `NC_DEBUG_` constants.
  */
  const NC_DEBUG_EXCLUDED_HOSTS = 'nc_debug_excluded_hosts';

• Before this block of code add the following new block:

  case $this::NC_DEBUG_EXCLUDED_HOSTS:
      $reason = __('because `$_SERVER[\'HTTP_HOST\']` matches a configured Host Exclusion Pattern on this installation.', SLUG_TD);
      break; // Break switch handler.

• Add a new UI config panel with the title "Host Exclusion Patterns". This should be available in both the lite and pro versions of the software, but only shown if is_multisite(); i.e., only for Network installations that may have more than a single host that needs to be cached.

  In addition, add a filter so that this panel can be shown on standard WP installations in special cases.

  if ($this->plugin->applyWpFilters(GLOBAL_NS.'_exclude_hosts_option_enable', is_multisite())) {
      // Display option panel for Host Exclusion Patterns.
  }

  Time-saver: This panel should appear just before URI Exclusion Patterns and you should be able to copy that existing panel and then adapt it for Host Exclusion Patterns. It will be nearly identical.

It would be nice if we could add a new Comet Cache Option panel for Multisite networks that would allow a network admin to exclude Comet Cache from certain sub-sites.

It's also worth noting that URI Exclusion patterns that already exist in Comet Cache can be used to exclude certain child sites if the network uses sub-directories instead of sub-domains.

A MS Network installation can be configured in one of two ways:

• main.com/child-blog/
• child-blog.main.com

Via URI Exclusion
